What is the transformer? A transformer is a static, passive electrical device that transfers the electrical energy galvanically between two or more circuits. The changing current in a coil produces a changing magnetic flux in the same coil, which in turn induces a varying emf (electromotive force) across another winding, wounded on the same core. […]

Ever faced the continuous failure of many electrical or electronic gadgets or appliances suddenly happening over a small period. Yes! You are right. It happens with many of us. It so happens that within a few months, we got replaced many of our appliances, without even knowing why it is happening. And, as long as […]

Power transformers are at the heart of all modern systems. Without electricity, the world can’t run, and without transformers, the electrical system can’t be thought of. Do you know what’s in the heart of these transformers? Yes, you got it right! It’s the windings of the transformers, without which they can’t work. These windings are […]

We all like savings. Don’t you! Saving is something that instantly raises our interest, light a bulb in our mind, alert us and make us more attentive, irrespective of the source from where it’s coming. It’s rather more soothing when it’s coming from some unknown source which we don’t know and don’t even believe that […]

A transformer has been defined as a static electrical machine that transfers AC electrical power from one circuit to the other circuit at a constant frequency, but the voltage can be increased or decreased depending on the requirement. This static device transfers electrical energy from one circuit to another through the process of electromagnetic […]

Using electrical equipments has become an indispensible part of our lives and imagining a life without these electrically run equipment sounds impossible. But have you ever pondered how do we get electricity from the power plants to our homes? We often take electronic devices for granted and plug them into the nearest outlet at our […]

A Transformer is a static apparatus which transforms electrical power from one circuit to another with no moving parts. It performs its action with the changes in voltage and current and no change in frequency. The main function of a transformer is to transfer AC electrical power from one circuit to another circuit […]

Voltage fluctuations both upwards and downwards are a common site in most Indian places due to an inconsistent power supply. These voltage fluctuations have a damaging effect on our electrical appliances, which reduces the normal life of these appliances. When the voltage of the house reduces, the electric current in the appliances spikes up, this […]

No of electric field lines passing through a closed surface – unit Voltmeter A transformer is an ideal device to relay current from primary to secondary. It works on the principle of induction created by the magnetic field of coiling. A transformer works on the principle of magnetic induction. It consists of a winding that […]

Before beginning to explore the world of electricity and voltage fluctuations, it is essential to understand the basics of voltage. Voltage is the basic building block of electricity that can help you understand the manipulation and utilization of electricity. Voltage is the driving force of current; it is the electromotive force that pushes free electrons from […]
